My invention is concerned'with adjustinglevers, sometimes called sp1-ag levers,'and

each of the positionsl of adj,ustment"ofl the lever; (3) thel wire connection tothe abutment is such that it will readi-lygripa plurality osizes of.' wire; (1i) the yparts are designed so that they are all stampings or automatic screw machine work, so that it can be ymanufacturedV quickly and cheaply; (5) it will be held yieldingly but ii'rmly 1n any adjustment; and (6) it can be mounted and be operative in anyxposition in Iwhich it may be supported.

To these ends, I have devised .the 'noveli combination oi"- elements which will be de` scribed at length in the specification and particularly pointed out inthe claims.

To illustrate my invention, l annex hereto a sheet of drawings,v'in wliichithe' same reterence characters are used to designate identical partsv in all the tigures, of wh1ch,-

Fig. 1 is a top plan view of a lever ern-Y bodying my invention;

Fin'. 2 is a,.centrallonvitudinal section on the line 2 2 of Fig; 1; and

Fig. 3 is a detail in .sect-ion on the line 8-3 of Fig. 1.

In carrying out my invention in its preterred form, l employ a fulcrum base 10, which is preferably a stamping made from heavy sheet-metal, and has the body portion shown in a horizontal position, although '1t may be mounted at any angle and extend 1n any plane desired. At the preferably square end ot the body l turn up a pair of ears 11, and between them I turn down an ear 12, these ears being perforated to receive Iscrews 13, by which the base is secured to any desired portion 11i of the vehicle or other device upon which it is mounted. Preferably riveted in the small aperture formed in the center of the body portion is the fulcrum pin 15 having the reduced lower portion 16 extending through said aperture. Surrounding the pin 15 and interposed between the head 17 ot said pin and the top of the lever 18 isv the helicallycoiled expanding` spring 19, which serves to Vhold the lever normally parallel with the'baselO'and with theratch'ettooth 20"'struclr from its underl side, extending into the desired one ofthe plurality ot: detent" aperturesl 21which are stamped out of: the 'body of the base 10 and extend in the arc of acircle concentrically with the pin' 15."

lVith` then construction shown, itwill be obvious ythat the'lever'18`ca`n beswungclockwise without substantialv effort', and thatit will be'v heldv in any advance position to; which it may be moved by reason ofV the engagement ofthe ratchet tooth 2O with the aperture y21 in which it Vis left. When'it' is .desired to release the lever, it is lifted tothe *Y dotted-line positioir shown `in Fig. 2, whenl it canbe .swung baclzfanti-cloclrwise' to its initial position. Y v

These sprag levers are provided With means ir'orsecuring thereto a"wire 22, leading to the carburetor valve or other device they are intendedfto control, and as this wire is taut, it is desirable to permit the: plug 23 to which it is' attached .to swingupon'the lever. rIt is also desirable to beablev to ad'- just the position of thef plug 23-to and 'from the Jfulcrum pin 15, so that the throw ofthe wire duet'o each amount'ot'angular movement. of thelever v18`can be varied, and it. is also: desirable to provider lthe plug 23 with'meansI torrgripping'- any sizedl Wire and for connecting the Wire or adjusting 'the position of the plug without detaching it. entirely from the lever 18. I secure all this desiderata by` the following simple construction:

The plug 23 has the cylindrical body portion with the transverse aperture 24- passing therethrough, which is of sufficient size to permit the passage of the largest size wire 22 which it may ever be desired to use. I reduce the diameter ot the lower portion 25 ot the plug 23 and pass a threaded aperture through said reducedportion into the transverse aperture 24e so that the machine screw 26 may be screwed upward with its end extending into the transverse aperture 2st as tar as may be necessary to grip the wire 22 Vbetween the top ot the transverse aperture andthe end of the screw. The aperture2` in the lever 18 consists of a plurality ot' large portions 28, which are ot suiiicient diameter to receive the reduced end 25 of the plug 23 and are connected by narrower necks or passages which will vpermit the passage ot the body 4oi the screw 26 but not the reduced end 25. Viith this construction, it will be obvious that the position of the plug 23 may be quickly adjusted simply by screwing out the screw 26 tar enough so that the reduced portion 25 may be lifted out of the large portion 28, so that the plug 23 can be moved longitudinally of the lever to bring the reduced portion 25 into the desired large portion 28, when the screw 28 will be screwed up to catch the wire It will be noted that the length of the screw 26 is greatenough so that when it is tightened up on any size wire 22, the reduced portion 25 will be drawn down into the chosen large portion 28 so as to hold it in place, while permitting the plug 23 to turn as much as may be necessary in the swinging of the lever 18.

/Vhile I have shown and described my invention as embodied in the form which l at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that l do not desire to be limited in the interpretation ot the following claims except as may be necessitated by the state of the prior art.

What l claim as new, and desire to secure by Letters Patent of the United States, is:

l. In a device ofthe class described, the combination with a fulcrum base, of a lever pivoted thereon, means for holding said lever in a plurality of positions, a wire-holding` plug pivotally mounted on the lever, and means'for adjusting the distance of the plug from the fulcrum without detaching` the plug from the lever.

2. In a device of the class described, the combination with a ulcrum base, of a lever pivoted thereon, means for holding said lever in a plurality of positions, a wire-holding Aplug pivotally mounted on the lever, and

means for securing the plug rotatably on the lever and at the same time the wire in the plug.

3. In a device of the class described, the combination with a ulcrum base, ot a lever pivoted thereon, means t'or holding said lever 1n a plurality of positions, a wire-holding plug pivotally mounted on the lever, said plug having an internally-threaded reduced portion extending through an aperturerin the lever and a transverse aperture, and a screw threaded through the reduced portion ot the plug into the transverse aperture.

4. ln a device of the class described, the combination with a ulcruin base, ot a lever pivoted thereon, means for holding` said lever in a plurality of positions, a wire-holding plug pivotally mounted on the lever, said plug having an internally-threaded reduced portion extending through an aperture in the lever and a transverse aperture, and a screw threaded through the reduced portion ot the plug into the transverse aperture, said aperture in the lever consisting of a plurality or large portions into whichY the reduced por tion of the plug may extend and connected by narrower portions through which only the screw can pass.

5. In a device of the class described, the combination with a sheet-metal ulcruni base having a plurality of supporting ears turned at an angle to the body thereof together with a central pivot and a series of detent apertures through the flat base arranged in the arc of a circle concentric with the pivot, ot a lever fulcrumed on the pivot and having a tongue extending downward therefrom into the plane of the detent apertures, and a helically-coiled expanding springinterposed between tli-e lever and the head of the pivot.

In witness whereof, Ihave hereunto set vmy hand this 16th day of January. 1922.
